Software / Performance Engineer

Quick Facts

• Role: Software / Performance Engineer (full-time or part-time for students)
• Focus areas: low-latency streaming, data analysis pipelines, and CDN cache architecture
• Environment: Linux-based development and operations

Description

You’ll help build and improve a large-scale CDN and streaming stack, including a low-latency livestreaming workflow and custom DASH/HLS packaging. You’ll also work on high-throughput event processing (e.g., Kafka to analytics stores) and on optimizing cache algorithms and HTTP/URL behavior in the CDN core. The role involves prototyping, experimenting with specs, architecture adjustments, and performance/debugging.

Responsibilities

• Prototype and experiment with streaming/data systems and specifications
• Debug and optimize performance across distributed components
• Improve CDN caching logic and related HTTP/URL behaviors
• Work on failover scenarios and debugging of connections between services and origins
• Contribute to distributed data pipelines and indexing/aggregation/compression

Benefits

• Pay aligned with experience, performance, and expectations
• Young, high-talent team with strong learning culture
• No corporate BS: trust, freedom, and no investor/management-driven work
• Office in a historic villa with garden (dog-friendly)
• Free breakfast and lunch; fruit/snacks/fresh juices
• Equipment tailored to your needs (laptop, monitors, headphones, etc.)
• Spinalis health chair and standing desks
• Free in-house barber

Requirements

• Logical and analytical thinking
• Enthusiasm for automation and solving “impossible” problems
• Basic theoretical CS knowledge (data structures, algorithms)
• Knowledge of at least one language: C/C++, Go, Lua, or Rust
• Experience with Linux for development and operations
• English level at least B2 (no certificate required)

Nice to Have

• Debugging experience (top, lsof, gdb, strace, etc.)
• Practical kernel debugging and finding performance bottlenecks (e.g., eBPF)
• Advanced Linux OS knowledge
• Knowledge of TCP/IP, HTTP, DNS, TLS
• Commits to the Linux kernel or any performance/debug-focused project
• Knowledge of “Systems Performance” by Brendan Gregg
